Black max 7kw generator high voltage output

Black max 7kw generator with 13 hp honda engine. While running in snow storm last winter quit producing voltage. Dried out and seemed to run ok and posered lights fine but i did not check voltage. Tried to run this week. Checked voltage and reads 145vac and 290vac. Hz is 62. opened the cover and conections looked good and clean, AVR looks to be hermetically sealed.

    I appreciate the tips and the help. Used both a True RMS volt meter and a simple meter. Results were less than a half a volt difference. A 60 watt bulb burned significantly brighter on gen power than on the utility. I adjusted freq exactly to 60Hz with no real change in output voltage. I must believe the voltage is high on the generator by a significant amount. I do not have a print of the circuit to aid troubleshooting. The generator does have a AVR. I am considering changing that as a start.

Those voltage readings MAY be normal.

The AC waveform may cause your meter to read inaccurately. You would need to use a TRUE RMS meter to accurately read the voltage.

The siple meters actually read the AVERAGE voltage and then are calibrated to mulltiply it by the "form factor" for a sine wave. OFTEN these generators don't produce a clean sine wave. A square-ish wave will read higher on the garden variety meters.

Compare the brightness of a lamp comparing to when run on your utility.

The frequency depends on engine speed ... yours is running a bit fast...check it under at least half load and if off, adjust the govenor slightly.

Testimonial: "Still working on the problem but tips were a real help."

  • Fred Yearian May 10, 2010

    That means that the waveform is good with both meters reading the same.



    Yes, the AVR must have a problem with its reference. Not sure if the components are accessable for replacement. I suspect that the driver transistor for the field MAY have shorted if this is a brush type unit putting full voltage on the field. If you can access the parts (if they are not "potted") it should be easy to find the bad component. The circuit will be rather simple so you might have to trace it out. A shorted driver will be found with an ohmmeter quickly. There probably would be a transistor driving the main one and that might be bad, however, the main driver would be the likely culprit because it is closest to where it can be damaged via transients.



    Finding a new AVR unit might be a hassle.



    The brushless types use a capacitor and the caps are usually pretty stable..

  • Fred Yearian Jun 10, 2010

    Glad it is working. You might think back if you did something to cause the failure like a sudden overload so as to avoid a repeat.



    Likely there is a semiconductor driving the field from rectified DC and that semiconductor probably shorted putting full voltage on the field. If you can open the AVR, it would be good to perform a post mortem on it.

Adustments engine speed low rpm


You cannot adjust the voltage output. All generators are rated for 110-125 volt recepticals and usually have at least one 220-240 volt receptical for special appliances that require it such as water heaters, pumps, welders, air conditioners. When one of these higher draw appliances is connected and they begin to draw amperage, the gas engine will automatically increase rpm to produce enough amps. If your generator gauge is showing low voltage such as 60,80 or 90volts for example, then you have overloaded the generator and blown a capacitor, resistor or similar item.

Honda eu3000is generator surges


Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

High voltage rpm power generator output


Not sure what you mean "high voltage rpm power generator out", however many people have asked how to adjust the engine for proper voltage output. On generators with~out a voltage regulator, I adjust the engine RPM by using a digital voltage meter that has a Hz setting. Adjust the governor untill the meter displays 60 Hz. With the geneator producing 60 cycles, I know that the engine is turning 3600 rpm (the engine produces max hp when it is turning 3600 rpm). At this point, read the voltage output to verify that the range is between 115 ~ 120. On generators with a voltage regulator, verify/adjust that generator is producing 60 cycles then adjust voltage by turning screw at the regulator (some regulators are sealed with potting compound and can not be adjusted). If your power demands are not that great and you appliance can operate at 50 cycles, adjust governor as needed. Lowering to 50 cycles will also reduce output voltage. Good luck

How often should the ignition coils be changed on a 2005 honda civic lx special edition? Thank you!


In ordinary use conditions, the ignition coils for your Honda should last a very long time--possibly the life of the car. It's not uncommon to see Hondas with their original coils at 125,000 or 150,000 miles--or more. New coils do put out a hotter spark than older coils, but in ordinary use, even an old coil should still be firing well within Honda specifications.

If your coils are getting fried early (meaning, a lot earlier than what I just wrote), you might want to check the voltage going to them. Too high voltage will burn them out prematurely. That, in turn, could be caused by a malfunctioning voltage regulator, and that same overly high voltage could also be burning out your bulbs and headlights prematurely, as well as possibly damaging your sound system and on-board computer.

When running, your car's electrical system should not be exceeding 14.5 volts. More than a few cars are designed to max out around 14 volts. Make sure that you check output voltage at several engine speeds, such as at idle, at 2000 rpm, at 4000 rpm. You might notice some variation depending on engine speed, but a good voltage regulator will do its best to keep output voltage consistently over 13 volts. Some Honda alternators and voltage regulators are designed to cut back on output voltage at low RPMs, i.e., when idling or just bopping around town. That would tend to give you a seemingly low reading, like a battery's own 12.6 volts; it would not give you a reading that's too high.

I have a honda generator em2500x voltage problem


My E2500 did this. Turned out to be dirt in the brush holders causing the
brushes to have less pressure in the slip rings. Stopping and restarting
joggled the brushes to make better contact until they wore down again.
Pull your brushes and make sure they slide easily in your holders. Also
you may need to replace them if they are worn too much or clean the
slip rings. Good luck. Doing your own repairs is fun.... especially when
they work.

Honda EMS 4500 Generator - High Voltage Problem


As far as I can tell on the wiring diagram for this generator there is no voltage regulator unless it's incorporated with the auto throttle unit.
To lower the voltage you need to lower the speed of the generator engine. To do this there should be a screw on top of the engine under the tank when your facing the recoil. This screw presses on a arm that controls your governor. Turning it in (righty tighty) will increase rpms, turning it out will lower them. You should see the voltage change on the voltmeter.

High voltage low cycles


I worked at a tool rental center while going to college and learned how to service generators. Most appliances/tools require 50 to 60 cycles at 110 to 120 v. Your engine was designed to give maximum horsepower at 3600 rpm. Adjust the engine speed to produce 60 cycles and the engine should be at 3600 rpm and producing around 120v max. (Some special generators were designed to produce 230v 180 cycles, check manual) If your generator incorporates capacitors check them for at least 95% of printed uf value. They should be removed from circuit for testing. If there are two caps and one is weak make sure the new cap reads close to value of remaining cap. Finally there is usually a voltage regulator that varies the power to the armature magnet trying to maintain steady voltage depending on amp draw and engine condition. This regulator has no adjustment and is pass or fail type of item. Good luck, enjoy

Honda generator em 1800


Honda generators are very reliable and are easy to adjust. The best way to check for proper output is to use a meter that can check cycles and voltage. Set meter to htz or freq and adjust the engine governor to 60 cycles. When the engine is turning 3600 rpm it is at max power and the generator may be producing ac voltage ranging from 115 to 125 at 60 cycles. When you draw power from the generator the engine governor will try to overcome the stress and maintain 3600 rpm. The engine must be well maintained to produce full power. Service oil, filter, plug and valve adjustment. Some engines have a spark arrester installed in the muffler that may become blocked with carbon. If engine is producing full power and voltage/amps is low then check brushes, capacitors, and/ or voltage regulator. Most problems occur when too much power is requested from rated generator. Example, trying to connect an 1800 watt air compressor to generator. The compressor may draw double the stated wattage upon starting and cycling. For longest generator life, It is best to use only 75% of rated output. On an 1800 watt generator use max wattage 1350. If you actually need to use 1800 watts then the best generator would be a 2500 watt. enjoy
